HOT-AIR REGISTER.

To ail whom it may concern:

Be it known that I, FRED H. DUDLEY, a

citizen of the United States, residing at Lincoin, in the county of Lancaster and State of Nebraska, have invented a new and useful Hot-Air Register, of which the following is a specification.

This invention relates to hot-air registers.

The objects of the invention are to improve and simplify the construction of such devices; furthermore, to increase their efficiency in operation and to decrease the expense attending their manufacture and instalment.

l Vith the foregoing and other objects in view, which will appear as the descrip ion proceeds, the invention resides in the combination "and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of inven tion herein disclosed can be made within the scope of the following claims without departe ingfrom the spirit of the invention or sacrificing any of its advantages.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of a register constructed in accordance with the invention. Fig. 2 is a side elevation, partly in section. Fig. 3 is a horizontal section, partly in elevation. Fig. 4 is an enlarged detail view, partly in section, of the spacing-frame and Fig. 5 is an enlarged rear elevation showing the upper corner of the register.

Like reference-numerals indicate corresponding parts in the different figures of the drawings.

The register-frame 1, which is adapted to be fitted against a wall, is formed with a rectangular opening 2 for the exit of the hot air.

7 Upon its rear face the register-frame 1 is provided with a pair of parallel vertically-extending supporting-flanges 3, which are disposed at the ends of the opening 2, as shown.

-The supporting-flanges 3 are formed at their upper ends with downwardly-extending op enended slots 4, which are adapted to receive the pivot-rod 5 of an extensible valve, which is indicated generally by the reference-numeral 6. The extensible valve 6 preferably consists of a main-valve section 7, which is in the form of a plate adapted to close the opening 2 and having its upper end bent or curled around the pivot-rod 5, as indicated Specification of Letters Patent.

at 8. The side edges of the main-valve section 7 are bent rearwardly to form guides 9, adapted to receive an auxiliary-valve section 10, which is adapted to slide vertically upon the main-valve section 7 between the guides 9. The means for sliding the auxiliary-valve section 10 upon the main-valve section 7, so as to secure the proper extension of the valve, preferably consists of a handle 11, which extends through a suitable vertical slot 12 in the main-valve section 7. It will be understood that the extensible valve 6, consisting of the sections 7 and 10 rests against the rear face of the register-frame 1 and that said valve is swung rearwardly and upwardly when it is desired to open the register.

The means for holding the extensible valve 6 in different positions, so that it will either deflect all of the hot air in the pipe 13 into the room or will permit a portion of said air to ascend to the next higher register while permitting the remainder to enter the room, preferably consists of a spacing-frame 14, which is capable of pivotal movement upon a pivot-rod 15, extending across the lower end of the opening 2 in the register and being connected at its opposite ends with the supporting-flanges 3. The spacing-frame 14 preferably is connected with the pivot-rod 15 by means of a bracket 16, which has its upper end 17 curled around the pivot-rod 15, as shown, and its lower end 18 bent to form an angular pocket, into which is fitted a fillingpiece 19. The spacing-frame 14 is connected with the bracket 16 and filling-piece 19 by means of bolts 20, having nuts 21. The bolts 20 in addition to their function of securing the spacing-frame 14 to the bracket 16 also serves to hold within each other a plurality of eccentrically-arranged rings 22, which are of different sizes and are disposed within each other, as shown, so as to produce a simple and inexpensive form of grille or open work spacing-frame. J

By reason of the fact that the pivot-rod 15 of the spacingdrame 14 is disposed at the upper end thereof it will be obvious that while said spacing-frame may be swung upwardly it cannot swing downwardly beyond a horizontal position, for the reason that the pocket 18 of the bracket 16 will abut against the register-frame 1, and thus limit the downward movement of the spacing-fl ame. When it is desired to adjust the extensible valve 6 so that all the hot air ascending the pipe 13 will be deflected into the room and none of it will be permitted to pass upward to the next higher room, the valve 6 is swung rearwardly and the auxiliary-valve section 10, by means of the handle 11, is moved downwardly upon the main-valve section 7 until the lower edge of said auxiliary-valve section fits down into the space between the rear edge of the spacing-frame 14 and the rear wall of the pipe 13. When arranged in this position, it will be apparent that hot air ascending the pipe 13 and passing through the grillework or eccentric rings 22 of the spacing-frame 14 will be deflected by the extensible valve 6 outward into the room. If it be desired to adjust the extensible valve 6 so that only a portion of the hot air will be deflected into the room and the remainder thereof will pass up to the next higher room, the spacing-frame 14 is raised up on an incline until the desired adjustment is secured and the auxiliary-valve section is adjusted upon the main-valve section 7 until its lower edge just contacts with the rear raised edge of the spacingframe 14. The weight of the extensible valve 6, bearing against the rear end of the spacing-frame 14, serves to hold the valve and the spacing-frame properly in adjusted. position.

hen it is desired to close the extensible valve 6 and to lock the same in closed position, so as to prevent the entrance of hot air v to the room, the spacing-frame 14 is dropped into horizontal position and the extensible valve 6 is swung forward. The auxiliaryvalve section 10 is raised with respect to the main-valve section 7, so that its lower end will clear or pass over the pivot-rod 15 of the spacing-frame 14. As soon as the pivot-rod 15 has been cleared the auxiliary-valve section 10 is moved downward upon the mainvalve section 7, so that its lower edge will enter the space or slot between the pivot-rod 15 and the register-frame 1. hen thus arranged, it will be apparent that the valve will be securely locked in closed position and that it cannot be opened except by manipulating the handle 11 to raise the auxiliaryvalve section 10.

The improved hot-air register of this invention is strong, simple, diuable, and inexpensive in construction, as well as thoroughly efficient in operation.

By reason of the fact that the pivot-rod 15 of the spacing-frame 14, consisting of the eccentric rings 22, is located at the upper outer corner of said frame, as shown, it will be obvious that whenever it is desired to clean the pipe 13 the spacing-frame 14 can be swung outward through the register-opening, so as to be disposed partly in the room, and thus permit any necessary cleaning instrument to be passed up or down the pipe.

l/Vhat is claimed is 1. A hot-air register comprising a registerframe, a spacing-frame, a pivot-rod for said spacing-frame disposed adjacent said register-frame to form a slot, and an extensible valve having an auxiliary valve section adapted to fit into the slot between the pivot-rod of the spacing-frame and the register-frame for locking said extensible valve in closed position.

2. A hot-air register comprising a registerframe having a pair of supporting-flanges formed at their upper ends with open-ended slots, a pivot-rod mounted in said slots, an extensible valve comprising a main-valve section having a slot and also having its upper end curled around said pivot-rod and an auxiliary-valve section slidable upon said main-valve section and having a handle pro-= jecting through the slot in said main-valve section, a second pivot-rod mounted upon said supporting-flanges near the lower end of said register-frame so as to form a slot adapted to receive the lower end of said auxiliary-valve section for locking the valve in closed position, a bracket having its upper end curled around said second pivot-rod and its lower end bent to form a pocket, a fillingpiece mounted in said pocket, a spacingframe having eccentricallyarranged rings of different sizes, and bolts extending through said rings, bracket and filling-piece for holding the same together, said spacing-frame being adapted to hold said extensible valve in different positions of adjustment.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
